JOHN LALLY, OF WALTHAM, MASSACHUSETTS.

COLUMN.

To all whom it mu/,I/ concern.-

Beit known that I, JOHN LALLY, a citizen of the United States, residinat Walthamin the county of Middlesex an State of Massachusetts, haveinventeda certain new and useful Column, of which the'following is aspeciiication, reference being had therein to t e accompanying drawings.

This invention relates to columns used in structural work, the object ofthe present invention being' to provide a novel form of connection orcap for columns the construction of which enables the same to be madeout of wrought iron or steel, thereby adding greatly to the strengthaanddurability of the column as a whole.

Afurther object of the invention is to provide aA cap v'or connection ofsectional construction, whereby the several parts of the same may be themore readily made up separately and then combined to form a strong capor connection especially ada ted for heavy work without increase of weigt inthe column itself.

A further object of the invention is to provide novel means forcentering and `accurately and properly associating the parts of thecolumn as a whole also, to provide novel means for anchoring or securingthe cap `or connection to the casing and bracing the parts relatively toeach other.

With the aboveand other objects in view the invention consists in thenovel construction, combination, and arrangement of parts herein fullydescribed, illustrated, and claimed. Y

In the accompanying drawings, Figure 1 is a vertical sectlion through acolumn embodying the present invention. Fig. 1 is a detail sectionshowing a slight chan e in the centering-plate. 2 is a vertica sectionsimilar to Fig. 1 showing another way of centering the parts. Fig,I 3 isa similar view illustrating another variation in the form of the cap orconnection. Fig. 4 is a similar view showing the entire cap orconnection madein one piece. Fi 5 is a similar section showing a slightmo ification in the anchoring means. Fig. 6 is a bottom plan view of thesectional cap or connection. Fig. 7 is a top plan view ofthe base whichrests u on the cap or connection to receive and ho d the upper casing orcolumn section. Fig. 8 is a vertical section throu h the same, showingthe manner in which t e said base is secured to the un- Specication ofLetters Patent.

i Application tiled September 25,1906. Serial No. 336,160.

Patented Feb. 5, 1907.

In the drawings, 1 represents the columncasing in the form of a hollow,and preferably cylindrical, shell designed to receive a filling ofconcrete in a plastic condition, which hardens therein and forms a solidfireproof construction.

superimposed upon the casing 1 is the column cap or connection whichembodies the beam-rest or crown-plate 2 and the reinforcingor,strengthening bracket 3, thelatter, under the preferred embodiment ofthe invention, being formed separately from the plate 2 and be' ofsectional construction. To this endthe racket part of the cap orconnection is constructed insimilarsections,

as shown in Fig. 6, in which it is seen that four sections are employed,each comprising an arcuate or segmental body part 4 and trian larbracing webs or flanges 5, which in ma g u the cap or connection arefastened together ace to face by bolts, rivets, orthe like, asindicatedv at 6; Thebottom ofthe plate 2 is channeled or recessed toreceive the top edges of the bracket-sections, as indicated in dottedlines at 7, said edges of the Section fitting snugly in the channels orrecesses provided in the plate 2 therefor and the parts being heldsecurely in the relation shown and described by the anchor hereinafterparticularly described.

The anchor 8 consists of' a pipe or tube of any desired length,havingone end thereof swaged outwardor flared to form a head 9,-

and the plate 2 is, formed with a central countersunk opening 10, inwhich the head 9 tits and iinds its seat, the construction andarrangement being such that the outer surface of the head of the anchorlies flush with the top surface of the plate 2, as shown, thus provi ingfor seating the superimposed base of the next higher column section orcasing thereon. The anchor 8 extends down into the casin 1, where it isrovided with a suitable num er of bond-ho es 11 and when the casing andthe hollow anchor are filled' with the plastic composition referred tosaid com- Iposition finds its way into' and through said oles, thefilling of the casing combining and knitting with the filling of theanchor, and a number of bonds being thus formed which permanently fastenthe anchor to the casing, while the anchor fastens the cap or connectionas a whole in place on the casin In associating the parts hereina ovedescribed a centering-plate 12 is interposed between the cap orconnection described and IOO the to of the' casing' 1, and, as shown in1 1, sai centeringeplate may be provided with l a fiange 13 at its outeredge, extending aboveand below the plate, within which the top edge ofthe casing 1 and the bottom edge of the cap Yor connection fit. Theplate 12 is provided with a central opening 14 of suitable size toreceive the anchor 8, and thus said Fig. 1, a flange may be located tolie within l the same arts, as shown at 17 in the detail section, Fig.1a, the sai-d lastnamed flange answering the same pur ose as the flange1,13. It is of course Wit-hm t 1e scope of this invention to employ bothflanges 13 and 17; but this is seldom necessary.

If desired, the cap or connection itself may be provided with a flange18, fitting into the upper end of the casing 1, as shown in Fig. 2,orwith a flange 19, fitting around the top of said easing, as Shown inFig. 3. Under the arrangement shown in Fig. 2 a shoulder 20 is provided,u n which the centering-plate is seated, wh-i e' .under the arrangementshown in Fig. 3 said centering-plate is inserted between the opposingkedges ofthe casing and cap or connection and within the fiange 19.

In some cases the entire cap or connection mag be made 1n one piece, asshown m Fig. 4, an provided wlth 'an integral flange 21,

l within which the centering plate 12 lies,

' lcasing 28 fits, as shown in Figs. 7 and 8.

interposed between the casing and cap or connection. The centering-platemay have a harige '22 on butone side thereof, as shown in Fig. 5,- andthe anchor instead of having the end thereof flared may bescrew-threaded .to receive a retaining-nut 23, while the crown-'plate 2may be recessed in its top face, as shown at 24, to allow thel said nutto lie within the plane of the top face of said plate, as shown in thesame figure.

Where another column-section is to be set 'upon the cap or connectionabove described, I employ a base-plate 25, provided with hol-'es 26,which line up with the holes 16 of the late 2, so that suitablefasteners, such as lts, may be inserted therethrough to secure the baseto the cap. Said base is provided 'with an 'u standing annular flange orhollow cylindrica body 27, around which the upper 29 designates beams orgil-ders which rest on the cap or connection, and 30 designates one of apair of`s`traps which pass around the oppo site sides of the column andhave their opposite ends bolted'or otherwise fastened to the beams orgirders, as shown at 31.

Another important feature of the invention resides in the employment ofa pin or dowel 32, one end of which extends down into -the anchor, andpreferably to a po1nt below. the centering-plate 12, the other endextending up into the superimposed base of the upper lcolumn section orcasing andas far as may be desired into the uppler caslng itself, whereitis embedded in t e filling. Where the flare-ended anchor is employed,the dowel pin may be provided with a correspondingly-shaped conicalvshoulder 355. to fit the flared end of the anchor, as shown 1n Fig. 8,and where the column is to be'subjected to special lateral Hor eccentricstrain the outer surface of the pin 32 may be corrugated, threaded, orroughened, 'as indicated in said figure, to obtain a more secure holdupon the filling within the cap or connection and the casings.
